Abstract

The crossing apparatus includes four armed crossing unit comprising an intersecting pair of current conducting members, and an elongated insulator attached to each of the arms and each of the wires. A conducting strip attached to each of the insulators is positioned to communicate with the current collector on passage of the vehicle and is of a length sufficient to allow successive simultaneous contact first by the collector with the wires and the conducting strips and then with the conducting strips and the crossing unit. Each of the conducting strips are electrically connected to the crossing unit. A polarity change switch device selectively provides electrical power of positive or negative polarity to the crossing unit. A contactor strip is positioned in close proximity to each of the crossing unit arms. The contactor strips are connected to the switch device and adapted to communicate with the current collector on passage of the vehicle to place the crossing unit in a condition of appropriate polarity. A diode is interposed between each of the conducting strips and the crossing unit to prevent transfer of power of opposite polarity to the conducting strips.
